What Are Radiographic Contrast Agents?
Radiographic contrast agents (RCAs) are substances used to improve the visibility of internal structures in imaging procedures, such as X-ray, computed tomography (CT), and fluoroscopy. They are classified into ionic and non-ionic agents based on their chemical properties and osmolality.
